Your home design and materials are required to achieve a 7 Star Whole of Home Energy Rating.
Generally our home designs and the insulation we use as standard inclusion achieve close to 7 Star rating.
A times for specific designs and sites, due to the orientation of the home, the window sizes and placements within solar orientations or even the colours selected can result in the Rating being less than 7 star. When the home does not achieve 7 Star, The Window Glazing and/or Insulation are upgraded at additional cost.
The new Whole of Home rating assesment is also resulting in most homes requring solar power systems of 1.5kw to 3.0kw.
Standard Insulation Inclusion is R6.0 Batts to Ceilings and R2.5 Batts to external walls.
